砂(sha)(sha)(sha)巖(yan)壁畫(hua)的泥砂(sha)(sha)(sha)巖(yan)還(huan)具(ju)有(you)類似塑(su)料的塑(su)變性(xing),更適合(he)雕刻(ke)和切出10mm厚(hou)的薄板(ban),關(guan)于砂(sha)(sha)(sha)巖(yan)輕微(wei)的塑(su)變性(xing),現普遍認為是(shi)SiO2之間分子聯(lian)結(jie)(jie),卻(que)又未形成結(jie)(jie)塊的緣故。砂(sha)(sha)(sha)巖(yan)的吸(xi)水(shui)率很大,一些品(pin)種(zhong)幾乎是(shi)將水(shui)倒上即滲(shen)入(ru)石材(cai)內,砂(sha)(sha)(sha)巖(yan)因其內部構造空(kong)隙率大的特性(xing),都有(you)吸(xi)聲、吸(xi)潮、防火、亞光的特性(xing),這種(zhong)特性(xing)的品(pin)種(zhong)裝飾(shi)到具(ju)有(you)吸(xi)聲要求的影劇院、體育館、飯(fan)店等公共場所效(xiao)果(guo)十分理想(xiang),甚至可省去吸(xi)聲板(ban)和拉毛墻。
